Coal Beneficiation Technology

Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. two basic processes of beneficiation: – dry-deshaling: non-coal or shaly-coal is removed without using any liquid.

Coal Properties And Its Influence On Boiler Pankaj Ekbote

Properties of coal • coal properties are evaluated by different methods. • the most commonly used methods are proximate and ultimate analysis of the coal. • proximate analysis gives the moisture, ash and volatile matter, while the fixed carbon is found by difference. • ultimate analysis gives the elemental composition of the coal. • other methods like macarel analysis is also used.
